RE VE RTIBLE-DRAFT STOVE Specification of Letters Patent.

Patented March 16, 1909.

Application filed March 2, 1968. Serial No. 418,785.

To all whom it may concern.'

Be it known that l, EMIL lt. S'I'Ascn, citizen of the United States, residing at Corning, county of Steuben, and State of New York, have invented certain new and useful Improvements in levertihle-Draft Stoves, of which the following is a specification, reference being had therein to the acconipanyinp,P drawing'.

This invention relates to a revertilzle draft stove, and particularly to a structure where the draft may he reversed through the Yfire as found convenient or desirable.

The invention has for an object to provide a stove structure einhodying a grate with draft o )enings ahove and helow the saine, and a flue. disposed at one side of said grate in communication with a flue plate and damper adapted to control the draft in either direction through the fire on the grate.

Other and further ohjects and :ulvantages of the invention will he fully set forth and the novel features thereof defined hy therappended claims,

ln the d1'awing:-lfigu1'e l is a perspective with par 1s in section showing' the down draft adjustment of the stove, and Fig. 2 is a siniilar view showing the direct or up draft Lilie numerals refer to like parts in the several views of the drawing.

The numeral l0 designates a stove or range which may he of any desired character or configuration, and is provided with the grate l l at one side of which the water hack l2 or other partition may he disposed and is spaced from the oven 13 to provide an indirect flue ,14 communicatingr with the usual draft flue lf3 at the top of the oven. Froni the top of the water hack or partition l2 a flue plate 16 extends parallel with the top 17 of the stove and forms a direct draft flue i8 communicatinpr with the top of the fire lvox, and a parallel 'flue 1Q communicating with the indirect flue 14. These llucs 1S and Il) are controlled by a single damper 2l) pivotally mounted at the free end of the plate i6, as shown at 2l, and adapted to close either of the flues when in raised or lowered position. For the purpose of limiting its travel lugs or projections 22 and 23 may he disposed u on the oven and top plate respectively, as s own.

For the purpose of admitting the necessary sir for combustion ol' the fire within the 'lire hoX 27, a draft dam er 24 of any desired character may he provifffid, such as the usual adjustable slidingplate, as illustrated. The ash pit 25 beneath the grate is also provided with a similar draft damper 26 to control the inlet of air at that point.

In the operation ol the stove, with the )arts in the position shown in Fig. l, the inlet damper at the top of the lire hoX is open and that at the ash pit closed, thus producing' a down draft through the 'lire u )on the grate which pa j'ses upward through die llue at thc rear of the water hack and out into thc chim ney flue., as usual. At this time the control ling damper for reversing' the draft is in u ward position to close thc direct flue from t 1e -fire hox. Under such operation the hody of fuel will hurn for an extended period maintaining' an even heat upon the oven, and hy heating hoth sides of the water haci; more quickly raises the water therein to the desired temperature. This arrangement also prevents thc escapi` of much heat with thc products of eornlnistion directly to the chin1- ney and draws downward the smoke and gases as well as the odors from the nmtcrial cool:- ing upon the stove and eifectually burns them so that the products of conil'nistion discharged are frcc from sniolie and soot thus preventing to a large extent the covering of the oven plates with a deposit of this character which diminishes the heat therein and cholaes thc draft lues requiring' frequent cleaning' thcrcol", W'hile it is desiralwie to maintain a down draft through the lire box under normal conditions, still in starting a fire a direct draft may be preferable and also for intense heat` and this can he effected hy closing' the upper inlet damper and opening; that at the ash pit, while the reversing' damper is swung' to close. thc indirect flue at the rear of the water back, thus musing an upward draft through. the lire and directly from the l'luc plate to the main lucy This liuc plato is extended laterally from the water hack or partition for a distance to remove thc reversing damper from thc effects of thc direct heat from the lirc hox and to pcriuit it lo cofipcrate with the lop plate ol the oven. 'lhc draft plate also extends acrosr` the top of thc indirect llue so as to throw said lluc into a parallel position to the direct draft lluc and thorehy prevent intcrfercm'c of one draft with the other. lt will hc seen that the invention presents a simple, ellicicnt and economically constructed arrangement of reversing' draft for cookinpy stoves adapted for application to ordinary stoves of this character.

Having described my invention and set forth its merits, what 1 claim and desire to cover by Letters Patent iszl. The combination with a stove having an oven therein, of a fire box spaced intermediate the oven and stove front to form an indirect llue and provided with draft openings and closures therefor above and below said box,y a direct flue from the to .i of said box, and a unitary damper mou ntecll at the intersection of said indirect and direct llues to control either thereof.

2. The combination with a stove having an oven therein, of a fire box spaced intermediate the oven and stove front to form an indirect Hue and provided with draft openings and closures therefor above and below said box, a direct flue from the to of said box, a iue plate extended laterally fioln the top of said iirc box and separating said indirect and direct fines, and a damper mounted at the free end of said plate to control either flue.

3. The combination with a stove having an oven therein, of a tire box spaced intermediate of the oven and stove front to form an indirect flue and )rovided with draft openings and closures therefor above and below said box, a direct flue from the top of said box, and a damper for controlling;r said flues.

4. The combination with a stove having an oven therein, of a iire box spaced intermediate the oven and stove front to form an indirect flue provided with draft openings and closures therefor above and below said box,

a direct flue from the top of said box, a dam per for controilin; said fluesr` and a water- )ack disposed at t ie side of said indirect iiue opposite the oven.

5. The combination with a stove having an oven therein, of a fire box having draft openings wlth closures therefor above and below sald box, the box belng spaced intermediate the oven and stove front to form an indirect flue communicating with the bottom of said lire box, a damper for controlling said flue, a water back disposed at the side of said flue opposite the oven7 and a flue plate extended laterally from said water-back intermediate the oven and stove top to form parallel ilues at that point.

6. The combination with a stove, of a fire- ".ox provided with a grate and having draft opemngs above and below said box provided with adjustable closures, an oven, a water back at one side of said box and spaced from the stove oven to form an indirect flue comt municating with thc bottom of said box, a

llue plate extended laterally from said water back mtermedlate the oven top and stove top to form parallel fines, and a damper plvotally mounted at the free end of said plate to close either flue.

7. The combination with a stove, of a lirebox provided with a grate havingr drafto )enings above and below said box provldcd with adjustable closures, an oven, a water back at one side of said box and spaced from the stove oven to form an indirect flue communicz'itingr with the bottom of said box,

a flue plate extended laterally from said water back intermediate the oven top and stove top to form parallel lines, a damper pivotally vmounted at the free end of said plate to close either flue, and abutments carried by thc under face of the stove top and the top plate of the oven to be engaged by said pivotcd damper.

In testimony whereof Vl affix my signature in presence of two witnesses.
